  • Title: [Interactive effects of drought and salt stresses on winter wheat seedlings growth and physiological characteristics of stress-resistance].
    Author: Chen CS, Xie ZX, Liu XJ.
    Journal: Ying Yong Sheng Tai Xue Bao; 2009 Apr; 20(4):811-6. PubMed ID: 19565760.
    Abstract:
    In a hydroponic culture, different concentrations of PEG-6000 (0, 8.3%, and 12.6%, W/V) and NaCl (0, 25, and 50 mmol x L(-1) were added to simulate different degrees of drought and salt stresses, aimed to study their interactive effects on the winter wheat (cv. Cang-6001) seedlings growth and physiological characteristics of stress-resistance. The results showed that under the conditions of adding 8.3% and 12.6% of PEG-6000, the addition of 25 mmol NaCl x L(-1) increased the dry matter accumulation and water content in plant, the contents of soluble sugar and soluble protein in leaf and the Na+ content in shoot and root, while decreased the MDA and proline contents in leaf and the K+ content in shoot and root, compared with no NaCl addition. Adding 12.6% of PEG-6000 and 50 mmol x L(-1) of NaCl more inhibited plant growth, compared with no NaCl added. It was suggested that under drought stress, applying definite amount of salt could alleviate the deleterious effects of drought stress on winter wheat seedlings growth.
